The model that is being studied is in a domestic pest that may be found throughout decaying food. The topic that is being examined is the Drosophila. When Drosophila is prepared for mating or hatching‚ they have a full lifecycle of about 20 days‚ thus are the models for relating sex-linked inheritance. Obviously it is not the breeding ways of the Drosophila that is being examined in this experiment‚ but the developing offspring‚ and their phenotypes. The phenotype is based on the wing shape and

Autosomal Inheritance of Wrinkled and black Mutations in Drosophila melanogaster Abstract Homozygous Wrinkled virgin females and homozygous black male Drosophila melanogaster‚ were crossed. Mutations were located on chromosome two and three respectively. The F1 generation‚ all Wrinkled and black‚ was inbred yielding and F2 generation. A phenotypic ratio of 9:3:3:1 was hypothesized with wrinkled wings and wild type body: wrinkled wings and black body: wild type wings and body wing: wild type wings

Introduction Drosophila melanogaster is a species of Fly (the taxonomic order Diptera) in the family Drosophilidae. The species is known generally as the common fruit fly or vinegar fly. Starting with Charles W. Woodworth’s proposal of the use of this species as a model organism‚ D. melanogaster continues to be widely used for biological research in studies of genetics‚ physiology‚ microbial pathogenesis and life history evolution. It is typically used because it is an animal species that is

Lab#3 Mendelian Inheritance in Drosophila Lab Report 1 In this experiment we are investigating the strength of the ratios discovered by Gregor Mendel in both the monohybrid and dihybrid cross. The ability to test these ratios stems from the use of Mendel’s law of segregation which states that during meiosis allele pairs will separate in gametes so one of each allele is present in a gamete. (Garey‚ et al‚pg 8-13) These single alleles are then combined with the other parental gamete forming

organisms ate much smaller and easier to care for and observe. A major advantage to using these model organisms are their ability to rapidly develop off spring often times in much larger numbers than a human. Some organisms produce The fruit fly‚ drosophila melanogaster‚ is one of the smallest model organisms used to provide insight to the genetic development of humans. Development biologists won a Nobel Prize in 1995 for the genetic studies and later principles they discovered with fruit flies that

The fruit fly Drosophila melanogaster are an excellent specimen for research in genetics. Many reasons are that they have a rapid reproduction rate‚ easy to care compared other animals and less expensive. Researchers have determined the nucleotide sequence of nearly the entire 120 megabase euchromatic portion of the Drosophila genome (Cite). Drosophila has a simple genetic arrangement of only four chromosomes which contains three autosomes and one sex chromosome according to(--) and because of this

Drosophila Melanogaster Introduction Drosophila mature through complete metamorphosis‚ as do all members of the order Diptera. [5] Diptera are commonly known as (true: having two wings) flies and include many familiar insects such as mosquitoes‚ black flies‚ midges‚ fruit flies‚ and house flies. [3] Drosophila melanogaster are most commonly known as fruit flies and are used in many genetic studies for a few simple reasons; they are small and easily handled‚ they have a short life cycle
